OP, your caster is too low. That range their alignment chart is showing looks wrong - It's below the Toyota spec. Low caster causes a vehicle to wander. The shop may not have set it higher because they thought it was in range, or they may have left it so low because they were unable to get more caster if you have stock UCAs.

The following is the proper caster and camber settings for an unloaded 2017-2021 Land Cruiser. This comes from the Toyota FSM, not some alignment machine. Note that the mid-point for caster should be 3.01 deg whereas the sheet they provided you shows 1.7 deg as the mid-point. Also tell the shop that you'd like 0.1 or 0.2 deg more caster on the passenger's side - right now the driver's side is more positive and that will cause you to drift to the right... you should have a bit more caster on the passenger's side to account for road crown so that you can let go of the steering wheel and the vehicle will track straight even though the road has a very slight arc to it.

Your camber is in spec but it's a bit high, especially for a lifted truck. That can also make your handling feel squirrelly as the front tires are not parallel but are actually set like a "V" with the bottoms pointed inwards. What's set is not technically wrong, but it will impact your handling. After the shop sets caster correctly, they should try to adjust camber to no more than +0.5 deg, and in my experience ideally a bit less

Tie-in looks good, btw.

I'd also recommend getting a few shock rebuild kits from Icon because you'll need them. Truck looks great, welcome!

I got my LC aligned today. They maxed out the stock arms and the specs are better. The steering is noticeably improved but not perfect. They suggested new UCAs and recommended Total Chaos HEIM joint UCAs. Around $1400 with labor. Do you have any thoughts on that brand? Thank for your help!

definitely one of the premier brands. SPC is adjustable and great value for what you are trying to accomplish.

Who is "they?" Those along with the Camburg and Icon forged uppers are the best out there no doubt.

Another 0.5-0.75 degree of caster would be nice. I'd also run less camber, somewhere around 0.2-0.3 degrees. More caster helps you track straight, more camber makes the steering feel lighter (so less camber makes it "heavier").

If you feel like it's better but not perfect and they've maxed out caster then I think you're on the right path but yeah your next step is a new set of UCAs. You can get a pair of SPC UCAs for under $600. I've been running mine for ~55k miles and I have no issues.

I think ARB, Dobinson's, and TrailTailor all offer non-adjustable UCAs where the additional caster is fixed. The plus side of SPC UCAs is that you can adjust caster and camber with them *in addition* to the normal cam adjustments that the techs do on the LCA. The downside is that you can adjust caster and camber with them in addition to the normal cam adjustments and many techs don't understand that (or are afraid to touch them). Mine are set with a bit too much positive camber right now - something easy to fix but the alignment shops around here (even the pro ones that do only alignments) don't want to touch it so I need to monkey with it when the weather warms up.

Of course you need an alignment afterward a UCA swap.

They are the guys at the off road shop that did the alignment
Thx

Great thank you! I looked at SPC about the same price as the Total Chaos for adjustable

I should have asked which shop specifically. SPC is highly touted on this forum buy TC, Icon, Camburg, OME, and Ironman are all very good options for UCA's.
